Chuck Colson relates this interesting story in his book How Then Should We Live?:

"In William Steig's Yellow & Pink, a delightfully whimsical picture book for children, two wooden figures wake up to find themselves lying on an old newspaper in the hot sun. One figure is painted yellow, the other pink. Suddenly, Yellow sits up and asks, 'Do you know what we're doing here?'

"'No,' replies Pink. ' I don't even remember getting here.'

"So begins a debate between the two marionettes over the origin of their existence. Pink surveys their well-formed features and concludes, 'Someone must have made us.'

"Yellow disagrees. 'I say we're an accident,' and he outlines a hypothetical scenario of how it might have happened. A branch might have broken off a tree and fallen on a sharp rock, splitting one end of the branch into two legs. Then the wind might have sent it tumbling down a hill until it was chipped and shaped. Perhaps a flash of lightning struck in such a way as to splinter the wood into arms and fingers. Eyes might have been formed by woodpeckers boring in the wood. 'With enough time, a thousand, a million, maybe two and a half million years, lots of unusual things could happen,' says Yellow. 'Why not us?'

The two figures argue back and forth. In the end, the discussion is cut off by the appearance of a man coming out of a nearby house. He strolls over to the marionettes, picks them up, and checks their paint. 'Nice and dry,' he comments, and tucking them under his arm, he heads back toward the house. Peering out from under the man's arm, Yellow whispers in Pink's ear, 'Who is this guy?'"

Colson then says, "That is precisely the question each one of us must answer, and it's no storybook fantasy. It is deadly serious. Beyond the public debates and rhetoric, beyond the placard waving and politicizing, at the heart of every worldview are the intensely personal questions: Who made me, and why am I here?"
